Myopia
What is myopia?
Myopia, also known as ‘short-sightedness’ or ‘near-sightedness’, makes it difficult for people to see objects in the distance clearly. Myopia usually starts at a young age and can continually worsen until adult years. Myopia occurs when the eyeball is too long and as a result, the light entering into the eye isn’t focused correctly.
Currently there are 2 billion people in the world who are myopic, and this is expected to grow to 5 billion by 2050.
risk factors
Family History
Ethnicity – Asians
Strabismus (Eye Turns)
Excessive close work (computer work and reading)
Poor lighting
Emmetropia at age 3
complications
High myopia (-5.00 or more) increases the risk of sight-threatening eye diseases and is now recognised as a major cause of blindness as it can cause:
Cataract, Glaucoma, Retinal Detachment, Myopic Macula Degeneration, Macula Holes, Retinoschsis, Choroidal Neovascularisation
Therefore it is important to try to control myopia progression to prevent these eye diseases.
controlling myopia
Orthokeratology Lenses (also known as Ortho-K Lenses, or OK Lenses
MyoVision Lenses
Atropine Eye Drops
Bifocal and Multifocal Glasses
Multifocal Contact Lenses
good eye hygiene habits
Good eye habits can reduce the stress on the eyes and in turn, prevent the progression of myopia.
Taking regular rest breaks with extended near work
Don’t hold your books, tablets or any other reading material too close to the eyes
Good lighting for all near work
Studies have shown that increased outdoor time, about 2 hours per day reduces the risk of developing myopic progression by 50%.
